The motive for his killing is still unknown, but it was likely that James had been mistaken for someone else.

More than a year on from his murder, officers continue to appeal for witnesses and information in an attempt to catch his killers.

Detective Chief Inspector Dave Bolton, of the Homicide and Major Crime Command , said: "James’s family has lived with the torment of knowing that his killer is still free for more than a year now.

"I am doing everything I can to change that.

"We are releasing images of two suspects we would like to speak to in connection with our investigation.

"I would urge anyone who recognises these people to contact us; all information will be handled in the strictest confidence and could be key in helping to bring a small level of comfort to James’s family."

A serious crime reward of £20,000 for any information leading to the arrest and conviction of any person or persons responsible for the murder of James Owusu-Agyekum is also still available.

Police had been called by the London Ambulance Service at 10.45pm following reports of a shooting on November 2 2016.

Local officers and firearms officers attended and discovered Mr Owusu-Agyekum suffering from gunshot injuries. He was pronounced dead at the scene.

A post-mortem examination on November 4 2016, at Northwick Park Hospital Mortuary, gave a cause of death as gunshot wounds.

Despite extensive efforts to find his killers, officers have not yet been able to locate them.
